Will a OCZ 850 Watt gold certified PSU enough wattage used in crossfire?CPU-6core AMD Zambizi, lots of fansRAM-G Skill X series 16 gB

I have a similar setup but 1000 watt. Doesn't seem to tax it at all so 850 might be enough.

When I purchased this graphics card, I had a 500 Watt power supply and had problems getting it to turn on. I replaced it with a 600w power supply and it fixed the problem. You should be good with the 850w power supply but I'm not sure how it will work in crossfire mode. It's a great product and I highly recommend it for prospective gamers

Yes definitely, and if you don't trust me or anyone else here, go to pcpartpicker.com and put in all the parts to see the estimated wattage. This PSU has 80% bronze efficiency so you should leave around 150W just to be safe.

Single card you can get away with a 750, the card draws about 350-375 watt sunder load, according to a comparison to the 970 and 980 cards, I just was reading today. I personally overshoot to make sure my PSU isn't working very hard. Example I have a dual card setup and i use a 1300w PSU EVGA.

I used a 650 W PSU, but it depends on your mobo/cpu requirements. I referred to the Puget Systems site for analysis and guidance. You are likely OK - I built in some headroom for expansion later.

It should be well more than enough to cover it. That combination, even overclocked, should use around 500W of power, taking into account everything you'll have in your system.

That's not what Sapphire says... I know the other person here said it was a lower power requirement card but in all honesty you should listen to the manufacturer when they tell you the minimum requirements. In this case this card requires at least a 500w PSU.

You need a PSU with 2-8 pin and 2-6 pin connectors for Crossfire, One 8 pin and One 6 pin for a single GPU.Yon should use a 850Watt PSU for a Single GPU, and a 1000Watt PSU for 2 GPU's. I have Corsair RM 1000Watt for my 2 GPU's.

Considering how this psu failed in 6 months when i have been doing heavy duty gaming.. I think the answer is no. But if you were asking if this unit can supply enough wattage for your build, the answer is yes. UNLESS you are running SLI/Crossfire, in which case go for an 750 or 800W.

I'm using a 430w Corsair cx power supply with a gigabyte r9 270 (note it uses 2x 6 pin instead of just one ) and its been running normally i am even able to overclock it without hassle. I'm even thinking in adding another card to crossfire. If you think 500w is not enough (which it should depending on what type of psu it is) you should look at this video: http://www.youtube.com/watch?v=ajiN9aVOv4A this is a high end power hungry build and it still barely even manages to get to 400w while STRESSING EVERYTHING INCLUDING CPU AND GPU TO THE MAXIMUM!! There is no need to get another psu, yet once again, i do have a 80+ bronze gpu and its rating do make it seem very reliable.

I found the wattage was not as important as the amps on the 12V rail. This card needs two 8-pin (or 6+2 pin) connectors, and my older 850 watt PSU ultimately did not have the right amps to support the card. (System kept shutting off... card had blown out the PSU.) 650 watts should be fine as long as your two 6+2 pin connectors off the 12V rail can support at least 20 amps each.

Yes sir. I am currently running 2 x AMD 7870's on it very nicely. The second PCI-E rail is even at 16x so should work fine with any crossfire set up.

This card can do a cross fire with an A10 6800K APU. I cross fired this card with the A10 6800K using the GIGABYTE GA-F2A85X-UP4 ATX Motherboard. However, when I installed it, I had to make sure that the UEFI BIOS enabled the GPU in the APU (basically just make sure you keep the integrated graphics enabled). It runs like a champ, it'll run several programs at once without a hiccup, and it plays several games using the high graphics quality settings.

The recommended system specs for this card is a 750 watt power supply. An 850 will do fine.

You won't want to go lower than 600w with this gpu and cpu especially if you plan on oc'ing or crossfiring, try to aim for 700-800 solid psu that leaves room for upgrades.

Your best bet is to google "PSU Calculator" and because they are all slightly different plus the components into each online calculator and see what they give you for a wattage count. Usually they are configured to calculate a 90% load. So whatever wattage you get is usually on the high end of your system running at near max conditions. My system running two of these with the FX 8350, 16gb RAM, 1 DVDRW, and Corsair H60 uses about 600w. However, start overclocking those cards and you can jump the wattage up quickly. I went to 850w psu to be safe but ran cards at stock clock

If you want to crossfire the gpu's then I would not recommend this power supply. If you are only running one gpu then this power supply would definitely suit your needs.

Yes, provided that the rest of the system (i.e. motherboard, CPU, other peripherals) are within the 850 Watt limit supported by this power supply.
